Properties of Modified Polylactides with Isosorbide |
| 초록 |
The incorporation of isosorbide into the polylactide (PLA) main backbone had a minor effect on the thermal stability and the degradation rate of the product. The previous study of the introduction of isosorbide into PLA have a limit to obtain high molecular weight due to the low reactivity of the secondary hydroxyl group of isosorbide. To overcome this, a modified isosorbide with ethylene oxide was used for a synthesis of PLA with isosorbide. The effect of PLA chain length of isosorbide-modified PLAs on physical properties was investigated. Thermal properties of the obtained modified PLAs were analyzed by differential scanning calorimetry and thermogravimetric analysis. Furthermore, their degradation rate was compared with that of PLA homopolymer with a similar molecular weight of copolymers by the Langmuir technique as functions of pH and enzyme concentration. |
